SPECIFICATION forming part of Letters Patent No. 413,447, dated October 22, 1889. Application filed August 3, 1839- Serial No. 319,674. (No model.) V

To aZZ whom it may concern.-

Be it known that I, CHARLES HILL, of Newark, county of Essex, State of New Jersey, have invented a new and useful Improvement in Machines for Winding Thread on Spools, of which the-followin g is a specification.

This invention relates particularly to means for controlling the mot-ions of the threadguide.

In Letters Patent of the United States No. 26,415, dated December 13, 1859, is described a thread-winding machine, which, with certain improvements added, that I do not know to have been patented, is commonly referred to as the Conant improved machine. In these machines it has been customary to give motion to the shaft bearing the thread-guide -by means of a snail-cam and other mechanism, so as t-opositively raise the thread-guide as the winding proceeded. The thread-guide was mounted upon the shaft, and the nose of the thread-guide over which the thread passed moved in a circle with the shaft as a center, the eifect being that the angle of inclination of the thread-guide varied at different stages of the winding, and as the nose of the threadguide' was lifted the angle at which the thread passed from it to the spool was rendered more acute, and the distance between the place of contact and the point of the guide was increased.

The object of my invention is to improve this machine by arranging the mechanism for moving the thread-guide so that the same shall as the winding proceeds be moved back from the spool in a direct li11e,so that the angle at which the thread passes from the nose of the guide to the spool shall remain constant at all stages of the operation.

Figure 1 is a plan view of the thread-Winding machine containing my improvement. Fig. 2 is a plan View enlarged, showing the thread-guide and the spool and the adjacent parts for supporting each. Fig. 3 is an end View of the same. through the line x m, Fig. 2, of the threadguide and other parts. Fig. 5 is a detail showing the mechanism connecting the snailcam with the shaft upon which the thread guide is mounted.

Fig. 4 is a cross-section tremity of which the spool is mounted in the.

usual mann er.

I) is the shaft which traverses backward and forward longitudinally as the winding progresses, and at the end of this is mounted the thread guide. The traverse changer and other parts for giving motion to "these two shafts are of the ordinary construction, and need not be herein particularly described,because no invention is claimed with respect to them. It is sufficient to say that the shaft a revolves continually, that the shaft 5' traverses so as to carry the nose of the threadguide from one end of the spool-barrel to the other, the length of traverse increasing each time to provide for the flaring flanges in the spool, and that the shaft 1), also with each change of traverse, rotates slightly in the same direction as the shaft a. lhis rotation of the shaft 7) is accomplished -by means of the snail-cam c, mounted upon the shaft of the traverse-changer, so as to be moved'only as the traverse-changer moves. A lever d, pivoted to the frame, rests at one end upon this snail-cam. A projection e on the lever d rests against one arm of the lever f, which is pivoted on the shaft 1), and upon the other arm of which the arm 9 rests. This arm 9 is made fast upon the shaft b'at one end, and at.

its opposite end is held down by a weight it. This weight tends constantly to rotate the shaft 1) in a direction to press the threadguide against the thread upon the spool, and

by varying this weight the intensity of suclr pressure may be varied at will.

1' is thespool.

j is the thread-guide. This thread-guide is slotted at j, and is secured to the face of a carriage it by means of a set-screw 7c passing through the slot of the thread-guide into the carriage. By this means the position of the thread-guide upon the carriage may be adjusted to accommodate spools of different diameters. The carriage 7a is mounted in dovetailed guideways upon the block I. This block is loosely mounted upon the shaftb,

but is compelled to traverse with it by being held between the shoulder b and the collar b as shown in Fig. 2. It is held from rotation downward by means of a rest m, extending under its forward end the full length of the barrel of the spool. This rest is supported from below from the frame of the machine. A flanged bolt 12 depending from the bottom of the block Z, prevents that block from rotating upward by the lapping of the flange upon the bolt under the rest m, as shown in Fig. 3.

dis an arm fixed upon the extremity of the shaft 1).

p is a lever pivoted upon the stud Z, depending from the block Z, One arm of this lever is coupled to the extremity of the arm by the link q. The other arm of the lever 15 p is pivoted to a rearward extension it from the carriage 7c. The pivot connecting p and works in a slot, as shown in Fig. 3, to provide for converting circular into rectilinear motion.

4 is a spring mounted upon the block Z, and bearing against the extremity of the rearward extension 70 from the carriage 70, thus tending constantly to thrust the guide j toward the spool.

l is a plate interposed between the carriage and one of its bearings in the block Z. This plate, being controlled by set-screws Z may be-employed to take up the wear.

The operation is as follows: The spool havin g been placed upon the spindle at the end of the shaft a, the threadguide having been adjusted .upon the carriage to suit the size of spool, the thread having been passed from the bobbin through the guide 3 and through the grooves s and s in the carriage and threadguide, respectively, and having been fastened to the barrel of the spool at one end, the machine is set in operation. The spool will be turned in the direction of the arrow, Fig. 3, and the end of the thread-guide will be held against the barrel of the spool by the pressure produced by the weight it and spring '7'. As soon as the thread-guide has completed one traverse of the length of the spool-barrel the movement of the traverse-changer will, through the snail-cam c and other mechanism before described produce a partial rotation of the shaft Z) in the direction of the arrow, Fig. 3. This motion is communicated through the arm 0, link q, and lever 23 to the rear extension k of the carriage it, moving the carriage back a short distance correspon ding about with the thickness of the layer of thread. The thread-guide now makes another traverse, at the end of which the same operation of moving back the carriage is repeated, and this occurs at the end of each traverse, so that on each succeeding traverse the thread-guide is moved back a distance approximating to the thickness of a layerof thread from the position which it occupied on the preceding traverse. The pressure of the thread-guide upon the thread is thus maintained uniform, and also the position which the thread-guide occupies with respect to the thread.

I do not desire to limit myself to the precise details of construction shown, since Iam aware that the form of construction will be varied to a considerable extent without departing from the principle of my invention, and I desire to cover all such modifications as may embody such principles.

I claim- 1. In a thread-winding machine, in combination, the spool-holder, the thread-guide, guideways supporting said thread guide, wherein the same may move back from the spool in substantially a rectilinear course, and mechanism whereby the thread-guide is moved back on such guideways at the end of the traverse, substantially as described.
